Ets-1、MMP-1及TIMP-1在膀胱移行细胞癌中的表达

目的研究Ets-1、基质金属蛋白酶1(MMP-1)及基质金属蛋白酶1抑制物(TIMP-1)在膀胱移行细胞癌(BTCC)中的表达及意义。方法用免疫组化方法检测40例BTCC组织和12例正常膀胱黏膜组织中Ets-1、MMP-1及TIMP-1的表达;分析Ets-1与BTCC临床病理特征间的关系;研究BTCC中MMP-1、TIMP-1表达与Ets-1表达的相关性。结果①Ets-1在BTCC中高度表达,阳性率为82.5%(P<0.01),且随BTCC临床分期和病理分级的升高而增加,肿瘤复发组高于无复发组,肿瘤转移组高于无转移组(P<0.05)。②MMP-1阳性表达率膀胱癌组(85.0%)明显高于对照组(58.3%)(p<0.05);TIMP-1阳性表达率对照组(83.3%)明显高于膀胱癌组(47.5%)(P<0.05)。③MMP-1与Ets-1表达呈正相关(Rs为0.824,P<0.01),而TIMP-1与Ets-1表达呈负相关(Rs为-0.821,P<0.01)。结论①Ets-1在BTCC中高度表达,并随BTCC分期分级升高而增加;Ets-1与BTCC转移及复发密切相关。②BTCC中Ets-1上调MMP-1表达,而下调TIMP-1表达,从而参与BTCC侵袭与转移。     

Schwangerschaft bei rheumatoider Arthritis oder Spondyloarthritiden

The activity of a rheumatic disease can be influenced by pregnancy and puerperium. Prospective studies have shown an improvement in joint involvement in rheumatoid arthritis in two thirds to three quarters of pregnancies. After birth, an exacerbation is common. In spondylarthropathies there is no relevant change in disease activity. The fetal outcome is not impaired in patients with rheumatoid arthritis and inflammatory spondylarthropathies. Every pregnancy in women with a rheumatic disease should be considered as high-risk, and such pregnancies require close collaboration between rheumatologists and obstetricians.

Localized Kaposi''s sarcoma in a patient with pemphigus vulgaris

We report the case of a patient with a 13-year history of pemphigus vulgaris (PV) treated with immunosuppressive agents, prednisone and mycophenolate mofetil who had developed lesions of Kaposi's sarcoma (KS) on a sole plaque of PV that had been previously treated with intralesional injections of steroids. The lesions were surgically removed and polymerase chain reaction (PCR) demonstrated human herpesvirus-8 (HHV-8) DNA. There were neither recurrences nor later dissemination of KS following gradual decrease of the immunosuppressive therapy. We suggest that the treatment with intralesional steroids may have influenced the local reactivation of a latent infection of the virus, determining the appearance of this localized KS.     

地塞米松促胎儿肺成熟的三种用药方式对母体糖代谢的影响

【目的】探讨地塞米松的用药方式对孕妇糖代谢的影响。【方法】对 1999年 9月至 2 0 0 1年 1月在本院住院的15 0名不同用药方式使用地塞米松促胎儿肺成熟的孕妇进行研究 ,在用药前及用药后 18～ 2 4h抽取肘前静脉血查空腹血糖、血浆C肽 ,糖负荷后 2h血糖、血浆C肽。【结果】使用地塞米松后 ,空腹血糖值、糖负荷后 2h血糖值、空腹C肽及糖负荷后 2hC肽值较用药前高 ;用药方式对母体空腹血糖值和空腹C肽值的影响差异无统计学意义 (P >0 0 5 ) ,对母体糖负荷后 2h血糖值和糖负荷后 2hC肽值的影响差异有统计学意义 (P <0 0 5 ) ;不同糖代谢状态的受试者使用地塞米松后 ,空腹C肽值、糖负荷后 2hC肽值的改变差异有统计学意义 (P <0 0 5 )。【结论】孕妇使用地塞米松促胎儿肺成熟对母体的糖代谢均有一定程度的影响 ,用药过程中和用药后需严密监测母体血糖和胎儿宫内状况
